Griner brake, A&A alum drum, Kevlar band, billet accum, coan supersprag, alto red eagle race clutches, billet input. Ive seen many a Cummins diesel over a 1000 hp and 2000 foot pounds. They are the same trans except the OD. They share the same inputs and clutches etc.. Now you take a 1000 hp diesel and lock it up after first gear and those will see more of a beating than these non lock up 727s.
